Teva Secures European Approval of Trisenox® for First Line Treatment of Low to Intermediate Risk Acute Promyelocytic Leukemia (APL)

Decision solely based on published academic data endorsing the
benefit of Trisenox® as first
chemotherapy-free treatment for APL and marks important advancement for
patients in Europe

EU Commission grants an extension of indication to first line use
of Trisenox®in combination with retinoic acid

APL0406 study revealed a 99% overall survival rate in low to
intermediate risk APL patients with first line treatment with Trisenox®
in combination with retinoic acid1

JERUSALEM--(BUSINESS WIRE)--Nov. 21, 2016--
Teva Pharmaceutical Industries Ltd., (NYSE and TASE:TEVA) today
announced it has obtained approval from the European Commission for an
indication extension of Trisenox® (arsenic trioxide). This
marks an important advancement in treatment for Acute Promyelocytic
Leukemia (APL) patients in Europe, as it is the first time that a form
of acute leukemia can be effectively treated with a regimen that is
entirely chemotherapy-free. APL is a rare and aggressive type of acute
leukemia that can kill within hours or days if left untreated2.
Trisenox®, in combination with retinoic acid, has shown a 99%
overall survival rate with almost no relapses after more than four years
(50 months) of median follow-up1.

“Teva is committed to providing wider access to high-quality medicines
to ensure more people can benefit from the treatments they need. We’re
very pleased by this decision of the European Commission, and we look
forward to offering a chemotherapy-free treatment option for all newly
diagnosed APL patients,” said Rob Koremans, MD, President & CEO, Teva
Global Specialty Medicines.

The decision by the European Commission, which follows a positive
recommendation from the Committee for Medicinal Products for Human Use
(CHMP) of the European Medicines Agency (EMA) on October 13, grants
marketing authorization for first line use of Trisenox® in
the 28 countries of the European Union. The indication extension is for
newly diagnosed low to intermediate risk Acute Promyelocytic Leukemia
(APL) in combination with retinoic acid. Today’s announcement points to
a recognition by the European Commission that treating low to
intermediate risk APL with a chemo-free regimen of Trisenox®
plus retinoic acid can increase survival rates, dramatically reduce the
risk of relapse, and help avoid chemotherapy-related side effects, such
as the risk of life-threatening infections.

Welcoming the approval, Francesco Lo-Coco, Professor of Haematology and
Head of the Laboratory of Integrated Diagnosis of Oncohematologic
Diseases, Department of Biomedicine and Prevention, University of Rome
Tor Vergata, Italy said, “This approval by the European Commission is
good news for APL patients as we now have access to a cure for an acute
leukemia without using chemotherapy. Moreover, this decision is a very
positive endorsement by the European Commission, as it was made based
solely on published academic research and studies. From now on, APL
patients with non-high risk disease will have access to this
chemotherapy-free regimen of Trisenox® plus retinoic acid at
diagnosis, which has the potential to increase survival rates while
minimizing side effects associated with chemotherapy.”

In Europe, approximately 1,500 to 2,000 people are diagnosed with APL
each year3. APL, a life-threatening form of leukemia, can
cause uncontrollable bleedingleading rapidly to death if
left untreated2.The rapid progression of APL
leading to early mortality is a substantial problem, affecting up to 30%
of patients4. Rapid diagnosis and commencement of treatment
is essential to avoid early mortality2,5.

About Acute Promyelocytic Leukemia

Acute Promyelocytic Leukemia is a form of acute myeloid leukemia (AML),
a cancer of the blood-forming tissue (bone marrow). Approximately 5% to
10% of patients initially diagnosed with AML present with the aggressive
sub-type of the condition, APL6.

In normal bone marrow, hematopoietic stem cells produce red blood cells
(erythrocytes) that carry oxygen, white blood cells (leukocytes) that
protect the body from infection, and platelets (thrombocytes) that are
involved in blood clotting. In APL, immature white blood cells called
promyelocytes accumulate in the bone marrow. The overgrowth of
promyelocytes leads to a shortage of normal white and red blood cells
and platelets in the body, which causes many of the signs and symptoms
of the condition.

People with APL are especially susceptible to developing bruises, small
red dots under the skin (petechiae), nosebleeds, bleeding from the gums,
blood in the urine (hematuria), or excessive menstrual bleeding. The
most important lethal bleeding sites are pulmonary (35%) and
intracranial (65%)7. The abnormal bleeding and bruising occur
because leukemic blasts produce anticoagulant factors and substances are
released that cause excessive blood clotting, leading as a consequence
to a low number of platelets in the blood (thrombocytopenia). The low
number of red blood cells (anemia) can cause people with acute
promyelocytic leukemia to have pale skin (pallor) or excessive tiredness
(fatigue). In addition, affected individuals may heal slowly from
injuries or have frequent infections due to the decrease of normal white
blood cells that fight infection. Furthermore, the leukemic cells can
expand into the bones and joints, which may cause pain in those areas.
Other general signs and symptoms may occur as well, such as fever, loss
of appetite, and weight loss.

APL is generally diagnosed in much younger patients than in AML (the
median age is approximately mid-408,9 for APL patients and 67
for AML patients10), and can be diagnosed in patients of any
age.

About Trisenox®

On 5 March 2002, the European Commission granted approval for the
Marketing Authorization Application (MAA) for Trisenox®. The
authorization, which was valid throughout the European Union (EU), was
granted to treat patients with relapsed or refractory acute
promyelocytic leukemia (APL) and characterized by the presence of the
t(15;17) translocation and/or the presence of the Pro-Myelocytic
Leukaemia/Retinoic-Acid-Receptoralpha (PML/(RARα) gene. Trisenox®,
a targeted drug, degrades the PML- RARα fusion protein. Trisenox®
received marketing authorization in 2000 by the U.S. Food and Drug
Administration.

The marketing approval for Trisenox® was granted based on
results from a multicenter study in which 40 relapsed APL patients were
treated with Trisenox® 0.15 mg/kg until bone marrow remission
or a maximum of 60 days. Thirty-four patients (85 percent) achieved
complete remission after two cycles. When the results for these 40
patients were combined with those for the 12 patients in a pilot trial,
an overall response rate of 87 percent was observed11.

1mL of Trisenox® contains 1mg of arsenic trioxide. Trisenox®
is a concentrate for solution for infusion. It is a sterile, clear,
colorless, aqueous solution. Trisenox® must be administered
under the supervision of a physician who is experienced in the
management of acute leukaemias, and special monitoring procedures must
be followed.

Post-induction events included two relapses and one death in CR in the
ATRA-ATO arm and two instances of molecular resistance after third
consolidation, 15 relapses, and five deaths in CR in the ATRA-CHT arm.
Two patients in the ATRA-CHT arm developed a therapy-related myeloid
neoplasm.
